摘要： PROBLEM TO BE SOLVED: To solve the problem wherein continuous monitoring of the degree of optical activity of the sample coming out of a filter after measuring inhibiting components in the sample is removed by the filter is useful to sense a steady state in the measurement of concentration for measuring the concentration of an optically active substance in the sample, by measuring the degree of the optical rotation of the sample but the concentration value of the sample easy to change, even if a steady state is obtained because continuously flowing sample is measured. SOLUTION: When it is sensed that the degree of optical activity becomes the steady state, feeding of a liquid is stopped for a fixed time, and the degree of optical activity of the sample in a stoppage state is measured again. As a result, the concentration of sugar in urine can be measured with high accuracy. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problems wherein, when trying acquisition of optical rotation in a wide range, accuracy is lowered, and on the contrary, when trying improvement of the accuracy, the range of the measurable optical rotation is narrowed, since the accuracy is lowered in proportion to largeness of a modulation width when using a method for modulating the optical rotation, in the case where the optical rotation by a rotatory material in a sample is measured.
SOLUTION: In this concentration measuring device for measuring the concentration of the rotatory material in the sample by measuring the optical rotation by the rotatory material in the sample, when calculating the concentration of the rotatory material in the sample from a light intensity signal after passing of the sample in a photodetector when the optical rotation of linearly polarized light entering the sample is modulated by an optical rotation modulation means, a modulation range of the optical rotation of the linearly polarized light by the optical rotation modulation means is changed, based on a detection signal by the photodetector, and a detection signal capable of calculating the concentration is acquired, and thereby highly-accurate concentration measurement becomes possible regardless of the intensity of the concentration in the sample.

摘要： PROBLEM TO BE SOLVED: To solve the problems in optical measurement by a conventional low coherence interference method, wherein adjustment of equipment needing extremely high precision is required, because of the need for mechanical operations, and the mechanical operation of moving a stage seriously affects on measuring precision, whereas as a means for measuring the concentration of a sample or the thickness of a transparent thin film, determination of its refractive index by the low-coherence interference method or the like is performed.
SOLUTION: The mechanical operation is replaced by an electrical operation, such as light modulation by a liquid crystal element, whereby the adjustment of equipment requiring very high precision is dispensed with, and precise measurement can be performed, since the influence of vibration or the like can be eliminated. Although the arrangement of equipment has seriously been limited in the past, because a mirror is made movable to use the reflected light by the mirror as the reference light, the liquid crystal element enabling the use of transmitted light is adapted, whereby a device configuration responding to various states, such as miniaturization, can be attained.

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein, in the case where the concentration of a rotatory material in a sample is measured by measuring optical rotation of the sample, especially in the case where the glucose concentration in urine is measured, when various measurement inhibition components included in urine are removed by using resins, high-rate recovery of glucose is difficult because the glucose is sandwiched physically between the resins by merely allowing the urine to pass the resins.
SOLUTION: After allowing the urine to pass a column filled with the resins, cleaning water such as pure water is allowed again to pass the same column, to thereby recover the glucose unrecovered at the urine passing time. In this case, since the measurement inhibition component is hardly included in the sample after passing, the glucose concentration in the original urine can be measured highly accurately without being influenced by the measurement inhibition component by measuring the optical rotation of the sample after passing.

摘要翻译：解决的问题为了解决在通过测定样品的旋光度来测定样品中的旋转物质的浓度的情况下，特别是在测定尿中的葡萄糖浓度的情况下，当通过使用树脂除去包含在尿液中的各种测量抑制成分时，难以高速回收葡萄糖，因为通过仅使尿液通过树脂，将葡萄糖物理地夹在树脂之间。
解决方案：使尿液通过填充有树脂的柱后，再次允许清洗水如纯水通过相同的柱，从而回收在尿液通过时未回收的葡萄糖。在这种情况下，由于测定抑制成分在通过后几乎不包含在样品中，因此通过测量经过后的样品的旋光度，可以高精度地测量原始尿液中的葡萄糖浓度，而不受测定抑制成分的影响。版权所有（C）2007，JPO＆INPIT

Further, the efficient reduction of contamination becomes possible by controlling the passing time of the component removing means 3 by controlling a valve 2. By this constitution, since maintenance work can be reduced and a measuring error can be reduced, highly precise measurement becomes possible. This measuring device is especially effective from an aspect for holding light transmissivity in an optical measuring system such as an optical rotation measuring system or a light absorption measuring system.
